CS3524A

Voltage Mode

PWM Control Circuit with

200 mA Output Drivers

The CS3524A PWM control circuit retains the same versatile

architecture of the industry standard CS3524 (SG3524) while adding

substantial improvements.

http://onsemi.com

The CS3524 is pin–compatible with “non–A” versions, and in most

applications can be directly interchanged. The CS3524A, however,

eliminates many of the design restrictions which had previously

required additional external circuitry.

MARKING

DIAGRAMS

The CS3524A includes a precision 5.0 V reference trimmed to ±1%

accuracy (eliminating the need for potentiometer adjustments), an

error amplifier with an output voltage swing extending to 5.0 V, and a

current sense amplifier useful in either the ground or power supply

output lines. The uncommitted 60 V, 200 mA NPN output pair greatly

enhances the output drive capability.

CASE 648

The CS3524A features an undervoltage lockout circuit which

disables all internal circuitry (except the reference) until the input

voltage has risen to 8.0 V. This holds standby current low until

turn–on, and greatly simplifies the design of low power, off–line

supplies. The turn–on circuit has approximately 600 mV of hysteresis

for jitter free activation.

Other improvements include a PWM latch that insures freedom

from multiple pulsing within a period, even in noisy environments;

logic to eliminate double pulsing on a single output, a 200 ns external

shutdown capability, and automatic thermal protection from excessive

chip temperature. The oscillator circuit is usable to 500 kHz and is

easier to synchronize with an external clock pulse.
